Flush valve



- quicken the fluShing of the bow1 and eliIninate oiated When it isundefStood that in this type of vvatef oloset the Siphon action istiIned to tefIni nate While the flush tank stin contains Sufcient watefto pfopefly fefi11 the ffap of the boW1,and the cofflpletion of thisfe11ing should ooincide with the en1pfying of the fioat chafnbef and theconsequent olosing of the valve 6, Whioh ifn n1ediately fonowS theoomplete en1ptying of the tank.

The valve 6 nlay be opened by any of the vve11 known Inanually fookablen1eanS that n1ay oon neof ith a veftioa1 feoipfooating lift-rod, 3s 9,Which fof thiS pufpose iS fofmed vvith a loop 9; the fod being S1idablein a peffofated lug 9o, Whioh may be integfa1 With the tube 5 and isprefefably fofnled vvith an oblique slot 9b that intefSectS thepeffofation, and enabIes a feduced poftion, aS 9o, to entef the S1otWhen aSSen1bling the paftS, as shoWn in ig. 8, By this oonStfuc tiof1,the fod vVhen later dispoSed efect and con nected vith the opefatingfneanS (see Fig. 1)-, iS not liable to eScape ffofn the 111g. The lovverend of fod 9 is pfefefably upset, as a,t 9Z, to pfo vide an integfa1head that engageS the lug and IiftS the valve steIn,

t has 1ong been the con1plaint of the pfeSent day type of ushing fin1Sthat the air nofnlany preSent in the oavity of the fiff1s beoonles entfapped by the initia1 floW of the fiuShing stfeam and must be expenedffom the fifn in ofdef that the fu11 volufne of the water n1ay bedelivefed to the boW1 to eect the pfopef Siphon aotion. To overoofne theback-preSSure cfeated by this en ffapped aif, the lattef haS to beforoed through the Sn1aH ofifices that oofnprise the sole exits fof theWatef frofn the fifn, ThiS not only TequireS an additional afnount ofvvatef and retafds the siphon aotion, but also ofeates annoying noisescon1Inon to nlost of the Inodern vvalter cloSets.

It fs an objeot of the pfesenf invention to pfeventing the ffee eSoapeof the entfapped air viaJ the said tube, aS indioated by the affoWS inPig. 6. In ofdef to acoon1pliSh the laSt-nanled objeot, advantage hasbeen taken of the SubStitution of the ovefffovv pipe 5, extendingthfough the valve 6, fof the solid Stefns in cofnfnon nse, The oper2ltion Whefeby the uShing of a cloSet bow1 iS fendefed quickef and lessnoisy is as fo11ows: when the valve 6 is initia,lly faiSed to staft thefluShing, and as long as the end 5 of pipe 5 fe hlainS below the planeof Sealt 3o, the flushing Water tendS to oW down the inner surface ofthe spud 3. This Inon1entofily establiShes a oleaf fiIle-1ike paSSoge inthe line of the oxiS of the spud thaf oommunicateS With the bofe of thepfpe 5. vvhen the Watef feaohes the uSual Sha11ow dis tfibuting ohanlbefwhioh acoofding to Iny foffnef patent lies difectly beneath thedischarge open ing 2 of the tank botton1 and con1nlunioates With thefifn oavity, the watef inStnt1y diSplaceS the oif oonned betWeen therin1 of the boW1 and the valve Seat 3ff, and the aif then takes theooufse of leaSt fesistanoe by aSoending thfough the Said fl11e andeScapeS vfa the bofe of the oveff1OW pipe o, as indioated by the affowsin Fig. 6. ThiS if1- Sfantly felieves the fifI of the back pfeSSufe, andallows the vvatef to f low ffeely and quietly thfough the exitS of thefifn af1d accelefate the oopious fiushing of the bowL by the tifnetheend 5 of the pipe 5 TiSes to the plane of the seat 3o.
